The HV winding is a multi-layer one for the lower ratings and two- or four-section multi-layer, block-coils or continuously wound disk hrafo for the higher ratings. This is our path through the years — a path of tradition and continuous renewal. Dial type – thermometer with alarm contacts over kVA. For more than 10 years now the plant has an established and certified quality management system acc. Type tests are performed on each transformer type.
The fitting elements bolts, nuts, washers etc. These are performed upon special request of the customer.
Off-load tap-changer driving mechanism 5. Lifting lugs on tank cover In the upper part the walls are welded e,prom a flange frame to which the tank cover is bolted.

Oil-draining and sampling valve DIN 9. Not exactly what you want? Special epoxy resin bushing and plug-in cable connector at the HV side Elastimold system optional. Axial bolts do the axial tightening of the windings. China for transformer China transformer kva rating China transformer. The thickness of the coating is increased depending on elpfom operational climatic conditions.
The voltage is regulated at the HV side by means of an off-load tap-changer when the transformer is de-energized.

High quality of the welding seams is guaranteed by tests with penetrating agents in a special test field and by testing with over pressure of 40 kPa. You, our customers know well that without solid foundation and clear goals there is no development, and we have both.
These include temperature rise test and lightning impulse test. Thus a sufficient thickness of the protective coating of min. The leads from the HV winding are insulated with thick insulation paper layer and insulation tubes and press board. The active part is lifted along with the cover by the lifting eyes situated on it.
Welding is done in protective atmosphere Ar-CO2. The quality procedures, according to ISO Nowadays we have control laboratories for incoming, current and outgoing control of the materials, used in the production, as well as testing laboratory for routine and type testing of the transformers.
TANK The standard type of the transformer tanks is rectangular a welded structure with corrugated walls made out of cold rolled steel sheets with low carbon content. The plant introduces a good working system, organized elpprom maintained by trsfo quality experts. The inner parts of the core and coil assembly are coated by an oil resistant enamel. The LV winding is situated at the core limb and is foil cylindrical type made out of profiled section copper for the ratings including kVA and out of copper foil for ratings kVA and above.
Each coat is dried up in electric ovens. The maximum production capacity of the plant has been reached before the end of the past century — 10 pieces of transformers are being manufactured annually.
We have special design and yrafo departments, thereby the production cycle becomes fully closed — from the design of the transformer to its assembly, in accordance with the requirements of the end customer and every related national and international standard.
